Static analysis reports this false positive
imx7-mipi-csis.c:1027:2: warning: 4th function call argument is
an uninitialized value
The variable 'align' is falsely reported as uninitialized.
Even though all the cases are covered in the
switch (csis_fmt->width % 8) {
Because there is no default case, it is reported as uninialized.
Improve the switch by converting the most numerous set of cases
to the default and silence the false positive.
